Honored ContributorThere is no syntax error when using [FILE *hostfile =fopen ("/mnt/host/song.mp3","rb");]. The reason why it returns NULL is that you have placed your song.mp3 at a wrong place.
Suppose your nios2 project is resided in "D:\altera\nios2\examples\vhdl\niosII_cyclone_1c20\standard\software\mymp3\", then you shall place song.mp3 in this directory. Good luck!
